Hello,
I have been looking around these forums and I have seen many people that have been HWID banned and feel like their only option is fork over money to buy spoofers from a third party. Most people do not know that all of the tools software required to spoof are completely free with a quick google search. The only real requirement is that you have a USB flash drive that is capable of downloading Windows and also flashing BIOS.
Here is a download link with all of the required software to spoof your HWID compiled into one folder

Here is the provided VirusTotal scan
EDIT: IMPORTANT!! This method now only works with windows 10 because Riot vanguard has recently started tracking TPM with HWID bans. You will need to be using windows 10 and disable your TPM in bios.
Step 1:
For your first step, you will need to redownload Windows and remove all files completely. I recommend using Windows 10 because Riot Games does not allow you to disable TPM with Windows 11. If you want to use Windows 11, that is fine but just keep that in mind.
Step 2:
Flash BIOS. You will need to go into your PC's BIOS and either upgrade or downgrade to a different version. Figure out the make and model of your motherboard and then search on youtube "How to flash BIOS enter name of motherboard".
Step 3:
Now that we reinstalled windows and flashed bios, we can go ahead and change serial numbers. Go into the serial changer folder and open DMIEDIT.
In System Information, you will need to change the UUID. Double click UUID and click Auto Generate Random UUID and click Ok.
In System Information, you will also need to change the Serial number. Double click the Serial Number and replace it with any random String of Numbers/Letters.
Go down the list Base Board/Module, System Enclosure, Processor Information and change the Serial Number to a random string of numbers/letters.
IMPORTANT: After you change the UUID and Serial Numbers you need to click Update>All at the top or else it will not save. After you Click Update>All you can close DMIEDIT.
Step 4:
We will now change the Serial Numbers of your SSD/Hard drives.
Open up the HardDisk application. Replace where it says Serial Number with random Numbers/Letters and click 'Change'.
Step 5:
Next, we will edit HWID registry keys.
Go to this website and generate 2 random UUIDs
In the search bar, type 'regedit' and open Registry Editor.
Go to this address and open MachineGUID and replace the value with your newly generated UUID.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography
Next, go to this address and open HwProfileGuid and change the value in between the brackets to your newly generated UUID.
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlS et\Control\IDConfigDB\Hardware Profiles\0001
Step 6:
Now we will change MAC address.
Download and open TMAC.
Highlight your Wi-Fi and click 'Random MAC address' and then click 'Change Now!'
If you are using Ethernet, also highlight Ethernet and click 'Random MAC address' and then click 'Change Now!'
Step 7:
If you followed each step carefully, your PC should now be successfully perma spoofed and no more VAN 152!!!
